A muntin clip supports a muntin grid inside an insulating glazing unit. The clip includes a positioning arm that allows the clip to be positioned with respect to the spacer. In one embodiment, the clip has a flat base adapted to be positioned on the inwardly facing surface of the spacer. The positioning arm extends from one side of the plate with the muntin-engaging body extending from the other side of the plate. The arm has an outer end that projects beyond the outer edge of the plate. A method for using the clip includes the step of using one of the glass sheets to engage and position the positioning arm of the muntin clip. Stops may be provided to limit the insertion of the clip into the spacer.
1. A muntin clip for supporting a muntin bar inside the insulating chamber of an insulating glazing unit having a perimeter spacer; the muntin clip comprising:
a body adapted to be connected to a muntin bar; the body having a spacer-facing side that defines an outer perimeter edge of the body;
a positioning arm extending directly from the spacer-facing side of the body; the entire positioning arm being in the form of a thin flat plate having an inner end, an outer end, a first edge and a second edge; the thin flat plate being adapted to be disposed in a slit defined by a spacer;
the positioning arm extending across the outer perimeter edge of the spacer-facing side of the body;
the first edge of the positioning arm being directly connected to the spacer-facing side of the body; the first edge of the positioning arm being disposed directly between the second edge of the positioning arm and the body of the muntin clip;
the positioning arm having a first width at the first edge of the positioning arm; and
the first width being substantially less than the distance between the first and second edges.
2. The muntin clip of claim 1 , wherein the inner end of the positioning arm is tapered to a point.
3. The muntin clip of claim 1 , wherein the positioning arm defines a smoothly rounded corner between the inner end and the second edge.
4. The muntin clip of claim 1 , further comprising a stop finger projecting from the body in a direction opposite from the projecting direction of the positioning arm.
5. The muntin clip of claim 1 , wherein the positioning arm extends across the outer perimeter edge in two locations; the positioning arm projecting from opposite sides of the body.
6. The muntin clip of claim 1 , wherein the positioning arm is centered with respect to the body.
7. The muntin clip of claim 1 , wherein the second edge is spaced from the first edge by a pair of opposed walls.
8. The muntin clip of claim 7 , wherein the width of the walls is substantially greater than the widths of the edges.
9. The muntin clip of claim 8 , wherein the width of the edges is 1 mm and the width of the walls is 3 mm.
10. A muntin clip for supporting a muntin bar inside the insulating chamber of an insulating glazing unit having a perimeter spacer; the muntin clip comprising:
a body adapted to be connected to a muntin bar; the body having a spacer-facing side that defines an outer perimeter edge;
a positioning arm extending from the spacer-facing side of the body; the positioning arm being in the form of a thin flat plate having an inner end, an outer end, an upper edge and a lower edge; the thin-flat plate being adapted to be disposed in a slit defined by a spacer;
the positioning arm extending across the outer perimeter edge of the spacer-facing side of the body;
the upper edge of the positioning arm being connected to the spacer-facing side of the body;
the positioning arm having a first width at the upper edge of the positioning arm;
the first width being substantially less than the distance between the upper and lower edges; and
a stop connected to the outer end of the positioning arm.
11. A muntin clip for supporting a muntin bar inside the insulating chamber of an insulating glazing unit having a perimeter spacer; the muntin clip comprising:
a body adapted to be connected to a muntin bar; the body having a base that defines a spacer-facing side that defines an outer perimeter edge;
a positioning arm extending from the spacer-facing side of the body; the positioning arm being in the form of a thin flat plate having an inner end and an outer end;
the inner end of the positioning arm being disposed within the outer perimeter edge of the spacer-facing side of the base;
the outer end of the positioning arm being disposed outwardly of the outer perimeter edge of the spacer-facing side of the base;
the positioning arm further having an upper edge and a lower edge;
the upper edge of the positioning arm being connected to the spacer-facing side of the body;
the positioning arm having a first width at the upper edge of the positioning arm; and
the first width being substantially less than the distance between the upper and lower edges;
the inner end of the positioning arm being centered with respect to the body; and
a stop connected to the outer end of the positioning arm.
